Exodus 4:27

25Then Zipporah took a flint, and cut off the foreskin of her son, and cast it at his feet; and she said, “Surely you are a bridegroom of blood to me.”

26So he let him alone. Then she said, “You are a bridegroom of blood,” because of the circumcision.

27The LORD said to Aaron, “Go into the wilderness to meet Moses.” He went, and met him on God’s mountain, and kissed him.

28Moses told Aaron all the LORD’s words with which he had sent him, and all the signs with which he had instructed him.

29Moses and Aaron went and gathered together all the elders of the children of Israel.
